Description

R25N Drilling Bolt Self Drilling Anchor SDA system for mining tunnel slope stabilization

The Self Drilling Anchor (SDA) system is a bolting solution for difficult ground and rock conditions. The system enables drilling and grouting in one operation, making much saving in jobsite and project time. Which is comprised of a hollow threaded anchor bar with a sacrificial drill bit that performs drilling, anchoring and grouting in a single operation. Self drilling anchor system is mainly used in slope stabilization, tunneling pre-support, foundations with micro piles etc jobs, which is widely used in mining, tunneling, railway, metro construction etc projects.

Applications

Tunnelling Ground engineering

1. Face stabilization

2. Radial systematic anchoring

3. Foundation for avalanche protect

4. Stabilization of tunnel portals

5. Spilling

6. Root piling
